feat(cli): support configuring the lock file in the config file (#16781)

This allows the user to completely opt out from the lock file or rename
it without having to use `--no-lock` and/or `--lock` in all commands.

## Don’t Use Lock File

```json
{
  "lock": false
}
```

## Use Lock File With a Different Name

```json
{
  "lock": "deno2.lock"
}
```

The CLI args `--no-lock` and `--lock` will always override what is in
the config file.
